Access web server on VirtualBox/Vagrant machine from host browser?

try this.

1. Open the vagrant file (should be in the directory you specified to create a new vagrant computer).
2. search config.vm.network. If you don't have a settings file before, you should comment it out.
3. Change it to look like this config.vm.network "private_network", ip: "55.55.55.5". The IP address here (55.55.55.5) can be any IP address you want.
4. Now logout from vagrant's computer and reload vagrant's computer with this command vagrant reload.
5. SSH to the idling machine again and restart the django server via this command python manage.py runserver 0.0.0.0:80. The port address (80) can be 8000 again if desired.
6. After that, enter the following address in your browser 55.55.55.5and hopefully you will see your web application.

Now, if you want to go a step further, you can edit the hosts file and add the following line

55.55.55.5 mynewdomain.com

Then enter the follow address in the browser,

mynewdomain.com

and you should see your web application. Note that www is not added to the domain name inside the hosts file, so only mynewdomain.com can be accessed. However, you can add it.

Hope this helps. cheers.
